secretion clearance

Question 1

Which of the following is NOT a cause of excessive secretions?

(a) loss of ciliated epithelial cells
(b) impairment of cilia function
(c) pneumothorax
(d) increased mucous production

Answer 1

(c) pneumothorax

Question 2

At large lung volumes, the equal pressure point is at the level of the small airways because air reaches further T/F.

Answer 2

False, it is near the trachea and mouth because there is more pressure in the alveoli, so it will be further along the respiratory tract before it reduces enough to be equal.

Question 3

The following move the EPP (equal pressure point) further down the respiratory tract EXCEPT:

(a) increased pleural pressure
(b) breathing in lower lung volumes
(c) increased expiratory effort
(d) breathing in higher lung volumes

Answer 3

(d) breathing in higher lung volumes

Question 4

the phase of autogenic drainage that brings secretions to the middle to large airways (ERV to VT) is:

(a) evacuating
(b) unsticking
(c) collecting
(d) none of the above

Answer 4

(c) collecting phase

Question 5

PEP breathing should take:

(a) 20 minutes
(b) 30-45 minutes
(c) 10 minutes
(d) 10-20 hours

Answer 5

(a) 20 minutes, it’s autogenic drainage that takes about 30-45 minutes, and 10-20 hours to learn the technique.

Question 6

PEP pressure should be about:

(a) 10 mm Hg - 20 mm Hg
(b) 15 mm Hg - 25 mm Hg
(c) 20 mm Hg - 30 mm Hg
(d) 25 mm Hg - 40 mm Hg

Answer 6

(a) 10-20 mm Hg.

Question 7

The main advantage of the flutter is that it can be used in any position, since it doesn’t depend on gravity like the acapella T/F.

Answer 7

False, it’s the acapella that doesn’t rely on gravity.

Question 8

The following clearance techniques require an inspiratory hold EXCEPT

(a) autogenic drainage
(b) ACBT
(c) use of a PEP oscillatory device
(d) none of the above - all techniques require an inspiratory hold

Answer 8

(b) ACBT
